Recent rumors on VideoCardz have revealed potential specifications for the RTX 5080 SUPER, following the rumored specs of the GeForce RTX 5070 SUPER and RTX 5070 Ti SUPER. It appears that NVIDIA will not utilize the larger "GB202" silicon for the RTX 5080 SUPER, opting instead to enhance the "GB203" silicon used in the current RTX 5080 with additional memory and power limits.
One notable feature of the RTX 50-series SUPER graphics cards is the inclusion of 24 Gbit GDDR7 memory chips. Similar to the RTX 5070 Ti SUPER, the RTX 5080 SUPER is expected to boast 24 GB of GDDR7 memory on a 256-bit wide memory bus.
NVIDIA may consider implementing 30 Gbps memory speeds for this SKU to achieve a bandwidth of at least 960 GB/s, matching that of the regular RTX 5080. Another intriguing aspect of the RTX 5080 SUPER is its anticipated increase in TGP (total graphics power) to 415 W, a 15% rise from the 360 W TGP of the RTX 5080. This higher TGP will not only accommodate the denser memory chips but also enable NVIDIA to boost GPU clock speeds. This adjustment is likely necessary as NVIDIA has limited room to expand shader counts on "GB203" and will require alternative methods to enhance performance for games with less demanding memory requirements.
